Inflatable Cuffs With Controllable Extensibility

Abstract:

A blood pressure cuff includes a support band that is selectively reconfigured between a flexible standby configuration and a measurement configuration. A blood pressure cuff includes an inflatable bladder, a support band, and a control unit. The support band is attached to and surrounds the inflatable bladder. The support band is reconfigurable, in response to an input from the control unit, from a standby configuration for between blood pressure measurements to a measurement configuration for constraining the inflatable bladder while the inflatable bladder is in an inflated state during a blood pressure measurement. The control unit includes a bladder pump for inflation of the inflatable bladder during a blood pressure measurement and controls the selective reconfiguration of the support band.
